Summary of the invention
The objective of the invention is to propose a kind of electrolytic recovery device, be used for handling the rinse water in the electroplating process, extract noble metal wherein, and remove cyanogen content wherein simultaneously, reduce cost of water treatment.
Electrolytic recovery device of the present invention comprises a container; Run through in the middle part of the base plate of said container a rotating shaft is installed; The top of said rotating shaft is equipped with one or more metal sheets of useing negative electrode as; Also be provided with in the said container and use the anodic metal object as, the sidewall of said container has water-in and water outlet; The bottom of said rotating shaft links to each other with PWR PLT; Said negative electrode with link to each other with the negative pole of power supply, said anode links to each other with the positive pole of power supply.
According to electrolytic principle; After containing the rinse water entering container of precious metal ions such as gold, its metals ion can be attached to cathode surface under the effect of electrode, simultaneously because electric current itself have the effect of heating; Can heat rinse water, so just can crack the cyanogen in the water.Use after for some time, just can reclaim noble metal as long as change the metal sheet of useing negative electrode as.In addition, metal sheet can rotate under the effect of rotating shaft and PWR PLT, and the rinse water in the container is formed stirring action, accelerates the separation of metals ion.
Further, the said metal sheet of useing negative electrode as is that pure titanium metal is processed, and in electrolytic process, need not to add any electrolysis promotor, to the quality not influence fully of liquid bath water quality and product.
Further, said water-in is arranged at the bottom of wall of container, and said water outlet is arranged at the top of wall of container.Like this rinse water can be from the bottom to top overflow container gradually, can guarantee the metals ion in the rinse water is separated absorption in the process the inside of overflowing.
Further, said container is processed for the PVC material.Because rinse water is mordant, therefore adopt protection against corrosion, insulation, resistant to elevated temperatures PVC material is made container can guarantee safety.
Further, said PWR PLT are the buncher that is installed on the container below, and said buncher is connected with said rotating shaft through belt.To different rinse water, can control the velocity of separation of precious metal ion through the rotating speed of regulating buncher.
Further, the said anodic metal object of useing as is for around rotating shaft and use the metallic cylinder of the metal sheet of negative electrode as.Adopt metallic cylinder as anode, can enlarge the anodic area as much as possible, thereby improve the separation rate of precious metal ion.
Further, PL, the switch that is used for control electrode work, the PL that is used to indicate the PWR PLT working order that is used for the indicator electrode working order, the switch that is used to control PWR PLT work are installed on the said container outside wall.Above-mentioned switch and PL are set can be helped to control the carrying out of electrolysis work and observe working order.
Further, said water inlet is equipped with adverse current and suppresses valve, to prevent the aqueous reflux in the container.
Electrolytic recovery apparatus structure of the present invention is simple, and volume is little, can be directly and the supporting installation of plating line, and the metals ion in the rinse water is separated timely, play Water purification, reduce the cryanide ion in the rinse water simultaneously, reduce the cost of enterprise operation.
